E-Wire Calc is an enamelled copper wire (magnet wire) tool based on the industry standards IEC NEMA or JIS. It provides several functions for the determination of various technical characteristics of the wire in the range 0010 - 08 mm or AWG 58 - 20 respectively.

The function DIAMETER allows the conversion of mm inch and AWG

The function RESISTANCE shows the nominal resistance for the given bare copper wire according to the set standard or calculates the diameter for the given resistance respectively

The function METALS allows the calculation of bare wire diameters of different metals for a given resistance.

The function RESISTANCE TOLERANCE shows the minimal and maximal permitted resistance for a given nominal copper wire diameter according to the set standard.

The function SIZES calculates the quantity of enamelled copper wire for a selected unit of length the length for a selected unit of quantity and the cross section for a given bare wire and outer diameter

The function BREAKDOWN VOLTAGE shows the minimal breakdown voltage of an enamelled copper wire with a given nominal diameter for different addition / increase classes.

The function WINDING TENSION calculates the maximal winding tension in cN recommended by ELEKTRISOLA for a given nominal copper wire diameter.

The function OVERALL DIAMETER TOLERANCE shows the minimal and maximal permitted outer diameter for an enamelled wire with a given nominal diameter in different addition / increase classes according to the set standard.
